The strong part of the drawing in space (and this goes back to my previous thoughts about constructing a Bach invention in C with thread and wire hanging across a room) is that it gives a strong experience of *being inside* the drawing, as opposed to looking at it from the outside.

With regards to this, experiments by Charley Peters with sunlight and drawing with white thread on the wall are of an extreme importance. The daylight moves across the room, instructing the behaviour of the drawing.

Listening to a musical piece, being in the music with attention of the mind, is, by analogy, a similar experience to being inside of the drawing. Having a drawing as a spatial object gives that extra bit of freedom to move around, - thus the audience's conscious decision instructs them on what kind of drawing they see.

As a note to self, further experiments have to carried out:

thread and wire (different thicknesses) in space - smaller and bigger models;
wall drawing and thread;
use of tape (black or limited colour?)
drawing and source of light
